SELF-CONTAINED BURNER DEVICE OF LONG ACTION Russian patent published in 2019 - IPC F23C99/00 F23L7/00 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering. Self-contained burner device with a long action comprises a body in the form of a cup, a built-in steam generator consisting of three units, namely an evaporator tank in the form of an annular chamber, a vapor separator in the form of an annular chamber and a superheater located coaxially with the housing of the device, as well as steam nozzle and nozzle located in gas generation chamber coaxially. Steam generator units are located in the burner device housing one below the other in the following sequence: evaporation tank, steam separator, superheater, in the cavity of the inner hole of the annular chamber of the steam separator there is a gas generation chamber, holder with steam nozzle and nozzle are installed in side walls of steam separator opposite to each other and so that steam nozzle is located in gas generation chamber, and nozzle connects gas generation chamber to ambient atmosphere, superheater is made in form of identical dimensions of cover and two flat disks with spiral channels, in the gap between the evaporator tank and the steam separator, a plug and four shutters are installed, each of which is 1/4 of the circular disk, wherein the shutters are installed on the upper end of the vapor separator so that movement from the periphery of the device housing to the center is pushed to the stop against the stopper, which makes it possible to close inner openings of evaporator tank and steam separator. Spiral channels of two flat disks of superheater have rectangular section and are made along trajectory of Archimedean spiral.

EFFECT: technical result is increase of autonomous burner device operation time due to its dimensions increase at maintaining energy balance.
